Arcane Rift

The Arcane Rift, also known as Guild Challenge, (colloquially: Rift and GC respectively) is a competitive and cooperative feature associated with Guilds. To participate, members must be part of a guild and a minimum of level 10.

The Rift consists of levels called "Floors". Each floor has a timer and a goal to slay a certain number of random spawning monsters, with the exception of floors that are a multiple of 10 and Seafood Floors [See 1.2 below]. Each time you complete a floor, you unlock one higher one. You can scroll between all the floors you have ever completed using the white arrows on either side of the screen. As new seasons roll past, you will get to keep your floor progress and continue to build on it.

If you should leave your guild or be kicked from it by the Guildmaster, you will have to restart your floor progress on floor 1. Rejoining the same guild will still reset you back to floor 1.

Floors that are a multiple of 10 will spawn two random bosses (including holiday event bosses). You have to defeat both bosses in order to pass these floors. Boss levels will vary slightly from the levels of monsters and may be above or below what you expect.

Floors that are a multiple of 4, plus 3 (4n+3) (e.g., 3,7,11,15,19...) will spawn sea creatures, useful for rifters, because the mobs don't have ranged attacks. These floors spawn more mobs than necessary for completion, and none* are stationary. (You don't lose time searching for them.)

Snails* (bar champions) will stop chasing you if they are hit out of their aggro range.

Higher leveled floors gradually offer more and more points for defeating the monsters within. Any member of a guild can play, but only the points from the top 10 members will count towards the guild's score. At the start of a new season, the guild score is reset to 0.

Typically scattered around the edges of a map, ancient pots can be destroyed to either restore 10% of your Health (85% chance) or contain a bomb that takes away 25% of your Health (15% chance). Both the heal and the damage are not affected by how much armor or damage reduction you have. Be careful, or stray area of effect skills could get you killed if you are unlucky and get too many damage-inflicting pots! Also, if a minion such as a snowkin from Summon Snowkin Snowldier destroys a pot, it will not affect the player.

Spawning monsters come from all parts of Terus. Monster levels increase as the floor number increases, but is capped at level 70.

Monsters spawn in waves, rather than with a delay, thus they may spawn as Champions, although they will not drop any Spirit Shards. (The Spirit Shards awarded upon successful completion of a floor have no correlation to the number of champions killed.) In addition, all champions in the Rift spawn as a single stand-alone monster, rather than the usual group of three encountered in regular zones. There is neither the horn nor visual indicator for champions that spawn in the Rift.

At the start of every floor, you are randomly assigned 3 blesses and/or curses. Blesses will increase your stats and have a positive effect overall, while curses can decrease your chances of beating a floor. Both blesses and curses stack additively. Since most blesses/curses are percentile increase, they will also stack additively with other percentile increases such as guild perks, set bonuses and equipment offering a percentile increase. For example, if you obtain a bless that increases your move speed by 25%, but also receive a curse that subtracts 50% of your move speed, your overall speed will be reduced by 25%, so you are moving at 75% of your regular speed.

All the curses/blesses have been grouped into their stacking categories

The speed at which your character moves can be affected, and will stack with other equipment, skills or items that increase the stat. Most notably, the Moonwalk curse is roughly equivalent to a -200% Move Speed debuff (which would be moving at -100% speed). That means if you get a 25% speed increase, you will actually be moving at -75% speed, which is to say, a slower backward walk! On the other hand, if you get an additional 25% speed decrease, you'll be moving at -125% move speed, which is a faster backward walk.

All armor blesses and curses affect your armor rating. The armor rating number is then subjected to a curve to determine how much actual damage reduction you have. In the case where you get more than 100% armor subtracted from you due to stacking of armor curses, your inventory will display a non-zero positive damage reduction, which is a visual glitch. You are actually being dealt more damage than usual with each hit you take!

The class stats Fury, Sorcery and Discipline can all be affected by blesses and curses. Since all of them can stack, you can receive as much as a 90% reduction, or as much as a 90% increase in a single stat. Only skill-based damage is affected by this type of bless and curse.

You normally gain 5 power per normal attack. The blesses and curses for this type will either add or subtract from this 5 power. For example, with a "gain 2 less power per attack" curse, you will gain 3 power per normal weapon hit instead of the regular 5 power. Skill-based power regeneration or consumption is not affected by any of these blesses or curses.

Prizes are awarded at the end of a season to the top 10 guilds. Every member of the winning guild, regardless of whether they participated in that particular season or not, will receive a crate at the end of the season, from which they can select their own prize. You are always guaranteed a chance to get a crate, but if you are lucky, you may receive a crate from a higher placement.
